First-principles engineering reduces unnecessary complexity. Fewer parts means each prototype is cheaper to build. Cheaper prototypes means you can build more of them. More prototypes means faster iteration. Faster iteration means you can push each prototype to failure without being precious about it. More failures means more data. More data means better designs. Better designs mean even simpler solutions. And the cycle continues

Until one is committed, there is hesitancy, the chance to draw back. Concerning all acts of initiative (and creation), there is one elementary truth, the ignorance of which kills countless ideas and splendid plans: that the moment one definitely commits oneself, then Providence moves too.
